Re: 60 Hz Tesla Coils

	Here are a couple of secondary designs which should work; the
parameters given are for no top-loading toroid.  With one the windings
wouldn't need quite as many turns.  The primary design is left to the
reader, but should be no big deal since it could be excited CW from a
pole pig.

SMALL COIL:

	Diameter	 	50 feet
	Length		150 feet
	Wire size:		#18
	Turns			42,755
	Inductance		7948 henries
	Capacitance		873 uufd
	Wire length		6,715,993 feet
	Weight		33,446 pounds
	DC resistance	42,882 ohms
	Estimated Q		70

	If that Q seems a bit low try:

BIG COIL:

	Diameter		90 feet
	Length		200 feet
	Wire size		10
	Turns			23,077
	Inductance		5381 henries
	Capacitance		1400 uufd
	Wire length		6,524,846 feet
	Weight		207,490 pounds
	DC resistance	6518 ohms
	Estimated Q		291

	These designs WILL work!  Who'll be the first to try one?  With all due
apologies to Evan and Joe, I predict one of these will be built before a
successful Newman motor is demonstrated to a discriminating public.
